969548 - Visual artifacts in tab bar

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

Attachment: duplicated new tab button

After a few days' use (opening and closing tabs, suspend/resume) I've start seeing visual artifacts in my tab bar (duplicated new tab '+' button).

I'm on Fedora 20 x86_64 running stock GNOME.

I'll work on a regression range.

This *just* started happening in the past few days but I can't get it to happen with a clean profile (or my existing profile with all add-ons disabled) :(

I'll try to muck with my prefs.js and see if it's something in there.

I have user_pref("layers.acceleration.force-enabled", true); in my prefs.js and it regressed somewhere in this range (mozregression is digging into inbound in this range):

http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=73eefb421e2a&tochange=5e0a22097bff 

My rough guesses which are likely completely wrong are that the offending patch could be in one of bug 940842 or bug 946502.

mozregression tells me bug 946200 is the culprit.
